Abstract

Based on 2 statistical testing schemes, the accuracy evaluation method of Time-SEP was proposed; 3 sphere error probability (SEP) methods were derivate and concluded. Simulation and experimental verification show that: Time-SEP method for navigation equipment positioning accuracy can give a relatively comprehensive evaluation; the scheme is feasible, compatible with the traditional calculation method of parameters and can fully utilize the single test data, test validation simple. 3 algorithms can all be used to calculate SEP, the maximum relative error is less than 5%; the χ2 distribution approximation somewhat conservative is recommended; and MLE values can be used as the initial value of integral operation, to reduce the number of integral operation, access to the true value rapidly.
